The invention relates to the technical field of sand washing mud treatment, in particular to a sand washing mud improvement method which is characterized by comprising the following steps: S10, coarse removal: treating sand washing mud through a cyclone and a circular screen in sequence, and performing coarse removal and fine selection on the sand washing mud; s20, acidity adjustment, wherein citric acid is evenly added into the sand washing slurry obtained after coarse sand removal, and the pH value in the sand washing slurry is made to be 5.0 or below; s30, dye preparation: grinding 90% of the components in the coal to 2 microns by using an ultrafine grinder, and using the ground components as the dye; s40, adding a dye into the sand washing slurry after acidity adjustment, and stopping adding the dye until the mixture of the two is yellow gray; original waste sand washing mud reaches the color and the pH value of mud for paperboards, and then the effect that the sand washing mud is suitable for papermaking is achieved.
本发明涉及洗沙泥处理技术领域,特别涉及一种洗沙泥改进方法,其特征在于,包括以下步骤,S10、去粗:将洗沙泥浆依次经过旋流器和圆筛处理,把洗沙泥浆去粗精选;S20、调酸度:去粗后的洗沙泥浆内均匀加入柠檬酸,使得洗沙泥浆内的ph值在5.0以下;S30、制染料:用超细研磨机将煤中90%的成分研磨至2微米,用做染料;S40、将染料加入调酸度后的洗沙泥浆内,直到两者混合物为黄灰色,停止添加染料;使得原本废弃的洗沙泥浆到达纸板用泥的颜色以及ph值进而实现洗沙泥浆适用于造纸的效果。
